""fWINDoWY Formar GAUGE Williamv M. Halif Stockton, Calif'. LV.lippi'iattimi Aprillmaseriallvo.66;.157'6 This invention Vrelates tothe carpentry art, and is particularly directed to a gage for accuratelyand quickly marking" out apattern for installation of windowpulleysfin.windowz frames. The

object of the invention is toproduce a gage of the character` noted inwhich the carpenter may, with very few manipulations of the gage, effectthe marking out of such patterns.

A further object of theinvention is toproduce such a gage which may beuseful in markingout the patterns where two different commonly knownstandard type of pulleys are usedw A still further object oftheinvention is to provide such a gage that may be used not only forcuttingI out the patterns `for Athe installation' of the pulleys, butalso may be used in related operations such as marking the correct bevelfor the window sill and for measuring and marking ofi materials to becut down in size.

A further object of the invention is to produce a simple and inexpensivedevice, and yet one which will be exceedingly effective for thepurposefor which it is designed.

These objects are accomplished by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claim.

In the drawings:

Fig. 1 is a perspective view of the improved gage.

Fig. 2 shows the gage as mounted on the window stile in the positon formarking `out the pattern of the pulley slots.

Fig. 3 is a similar view showing the gage as it would apear as it wasbeing moved down to draw the longitudinal center line for the pattern ofthe pulley slots.

Fig. 4 is a plan view of the window stile showing 4the patterns for thepulley slots after they have been delineated on the stile through theuse of the improved gage.

Referring now more particularly to the characters of reference on thedrawings, the improved gage comprises a relatively at plate I on oneedge of which is a guide flange 2 extending at right angles to the plateI. Blanked out of the plate 2 are slots 3, each slot being identicalwith the other and of a Iconiiguration conforming to the pattern of apulley slot to be cut into the window stile. Each said slot 3 comprisesan elongated rectangular portion 4 terminating at each end in asubstantially circular orifice 5 which registers with the portion 4. Inthe sides of the plate I adjacent each orice 5 are diametrically opposednotches '5, and at each outer end of each orifice 5 there is a notch 1;the notches 4'l inthe two opposed notches being diametrically'opposed toeach other and extending substantiallyl in line withthe longitudinalcenter line of the slot 3.

When the device is to be used it is rst determined what length thewindow stile `is to heA cut. The gage is then squared on the stile andthe lines are marked for the'sill. Proper measurements are then made forthe header, and -the stile is ruled off, as at B, accordingly. i

` The gage is then squared against thefstile with lthe edge of the gageon theinside of the header mark 8. i A marker line 9 is then drawn alongthe fbottom side of the gage. The gage `is then moved downwardly onthestile so that the upper side of the gage rests on the marker line. 9.vThis positions the gage at the exact place where the pulleys are to beinstalled.

A pencil Ill is then traced around the cut-out portions 3 so as tooutline the form of the slots l I to be cut for the pulleys, as shown infull lines in Fig. 4. While the gage is still in the position in whichthis outline has been made the pencil is placed in the upper notch 1.The gage is then drawn down over the stile, during which operation thecenter line I 2 for the pulley slots is drawn on the stile. The gage isthen placed with one edge extending across the configuration of thediametrically disposed notches which have been traced on the stile, andlines I3 are drawn across these points. This establishes the exactcenters I4 for boring the end holes 0f the slots for the installation ofstandard window pulleys. These are bored out and `then the connectingslots are cut out to form the complete openings for the reception of thepulleys. This establishes the practice used on one type of commonly usedpulley.

There is also another type of pulley known as the jam-proof pulley, inwhich a substantially rectangular slot is cut in the stile. When thegage is to be used for this purpose it is positioned as shown in Fig. 2.No outline of the slot, however, is traced. Instead, a pair of spacedpoints are marked 01T on the stile by inserting the pencil through smallholes l 5 which extend through the plate I. The gage is then moved downto these points and lines are drawn across the stile. The pencil is thenplaced against the sides of the portion 4 of the slot and the gage movedup and down in order to mark side lines on the stile. The pencil is thenplaced in one of the notches 1, and the gage and pencil is drawndownward to mark the center line for making the borings or other cutsfor the pulleys; such resulting cuts being of 3 the exact measurementsnecessary for the installation of the jam-proof type of pulley.

The gage may also be used for marking on the stile, the correct bevel atwhich it must be cut in order to t the Window sill. To do this the gageis placed onv the stile where the sill is to be located and the pencilprojected through holes I6 and I1 which extend through the plate l, andwhich are offset relative to each other nse that when a line is drawnacross 'the points thus marked x.on the stile this 'line `will beestablished on theirs-ual standardslant at which the window sillextends. This marking may be made by a try-square or 'by manipulation ofthe plate l.

The'gage may also be used for measuring `and marking off materials to becut draw-ri leirl eine. When this" is to be done there isprovidedrazruled edge yI8 which is deeply notched in -eiglIths-o`inches. The point of the pencil may hernia/eed in one of these notches,which indicates the 1reguired 'measurement-and the gage and pencil ,-isthan tdraav-n along the boaezd, thus laeonsately and quickly marking itifor planing for sawing.
